Cloud Connector Edition Upgrade Issues

Cloud Connector Edition

Since i was facing some isssues last time with upgrading our company Cloud Connector Edition it’s a good thing to keep old installers (check below for Archive).

We had the CCE 1.4.2 version running, due to some accounting issues the upgrade to 2.0.0 never has started. You can use Set-CcCredential -AccountType TenantAdmin to set the new global admin account. (Global admin role required for 1.4.2, from 2.0.0 and newer Skype Admin role is required) So after setting the right O365 account i tried to start upgrading the appliance.

Because of the release 2.0.1 the Start-CcDownload cmdlet started downloading the 2.0.1 installer. Started cmdlet Install-CcAppliance -Upgrade and after 1,5 hour the setup stopped with all kind of errors, no sql installed on Edge, certificate issues and so on.

Let’s Encrypt and Skype for Business

Let's Encrypt Skype for Business

For my home lab I’m using the free certificates from Let’s Encrypt (Let’s Encrypt is a free, automated, and open Certificate Authority).

The certificates from them have 1 big limitation, they are only valid for 3 months but you can renew them “almost” automatically.

As explained In my blog last week about “Skype for Business environment running with just one public IP” I’m running my Reverse Proxy with IIS ARR (Application Request Routing). I’ll try to explain how to request and assign the free certificates for your homelab.

What’s fixed in Cloud Connector Edition 2.0.1

Cloud Connector Edition

In Cloud Connector Edition 2.0.1, the following fixes were made:

Restarting Virtual Machines sometimes caused the service to stop if the restart order determined by Hyper-V was incorrect. This has been fixed.
Calls for download security checks in remote PowerShell sometimes caused calls to the New-CsOnlineSession cmdlet to fail. This issue has been fixed.

During automatic updates, switching to a new version sometimes caused the running version to fail. This issue has been fixed

You can download the new Cloud Connector Edition 2.0.1 is now. If you have not yet upgraded to 2.0.1, You can find the installation file at

Skype for Business environment running with just one Public IP

Skype for Business

For quite some time I’m running a home lab, first on a big server (HP Proliant DL360) and since beginning of this year I have a Intel Nuc, saves a lot of energy costs 😂

  • Domain Controller and CA on Windows 2016 Core Edition
  • Skype for Business Front-End Server on Windows Server 2012r2 standard
  • SQL 2014 std for monitoring and persistent chat on Windows Server 2016
  • Exchange 2016 on Windows Server 2016
  • Skype for Business Edge on Windows Server 2016
  • IIS ARR (Reverse Proxy) on Windows 2016
  • PBX on Windows Server 2016

This lab was great for testing purposes but the problem was always, no connection to the outside world with Skype because of the requirement for at least 2 external IP’s with the use of Skype for Business.

*** To be clear, DON’T use this for production environments, this is not supported by Microsoft ***

So I started searching on the internet, could not find much about setting up a Edge Server with just one nic or 2 nic’s in the same subnet.
Only on the site from Mark Vale I saw a blog article that he did the same setup with 2 nic’s and 1 public IP. The missing part for me was the Edge server configuration. How do I need to configure my networking. Check below to find out!

Powershell Enable / Disable / Set / Show Windows Web Proxy

I’m currently working for a company where I have to set up a web proxy to connect my laptop to the Internet. Because I’m a little bit lazy to enable/disable this every morning when i come in, or when i open my laptop at home, i use these two oneliners in powershell:


set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' -name ProxyEnable -value 1


set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' -name ProxyEnable -value 0

Complete Script:

I also created a simple menu script with all the options to Enable, Disable, Set and Show. You can download the script from Technet Gallery
